Description

Technical area

Computer system and device which quiz tasks for an Internet-based quiz can generate and manage autonomously, and can perform a quiz.

Presentation of the invention

State of the art

The Internet offers a variety of applications, one could be Internet marketing, which can be carried out by means of an advertising box or coupons. In the first case, the internet user determines the duration during which offers can be made. In the other case, the provider must grant large price reductions in order to mislead the Internet user to a purchase.

Games and quizzes are well-known alternatives and popular with young and old. A quiz allows players to stay connected to a website for longer. Therefore, companies and educational institutions have long been concerned with the use of quizzes for this purpose as a research has shown.

[0004] DE 19 961 546 A1, Method for Learning by Computer: The learner (e.g., student, student) is presented with stored learning lessons. This device uses ready-made learning lessons stored in a database.

[0005] EP 1 010 067 A2, Computer-implemented decision management system with dynamically generated questions and answer choices: This system supports a user in the decision-making based on a questionnaire. A database contains ready-made questions with which you can then create a questionnaire. This system does not create answers or quiz questions.

WO 2012/014 161 A1, Web-based questionnaire System and method: The user is asked a ready-made question and then given a hyperlink to a web page in which the user must find the answer within a given time. The answer is then compared to the stored answer and counted according to the match. This system uses a database of ready-made questions and answers.

IBM Watson, http://www.watson.ibm.com/index.shtml, as of 5/9/2012: This computer system can search for answers to questions in large databases and issue. The field of application is the medical diagnosis or the prediction of the development in the financial markets. This computer does not produce a quiz, does not compare answers, and generates responses from the processing of stored database information.

The published inventions and computer systems are used for education, or generate predictions (eg questions based expert system for doctors), or have the goal by means of a quiz with reward (eg discounted product, coupon, price) to create incentives for a long time to stay on a website.

disadvantage

Internet quiz, and knowledge quiz in particular, have usually stored the questions and answers in a database. In order to serve many visitors, or to ensure that returning visitors do not get the same questions, this database must be very large. A database-based quiz can compare players' responses only to the stored responses in a database. The uniqueness of multiple-choice answers makes this class of quizzes the rule and therefore the most common quiz. It is technically very easy to implement and therefore widely used. Creating a large database is expensive because it happens with manual help. These reasons limit the scope of application in the long term and thus prevent the use of (knowledge) quizzes for many applications.

task

The present invention extends or allows the use of a quiz for a wide range of applications without the disadvantages of traditional, i. E. purely database realized, quiz.

solution

The object is solved by the features of claim 1 and preferred embodiments can be found in the dependent claims.

advantages

The advantage of the invention is that (knowledge) quiz can be offered to a wider audience because there are many possible applications that the cost of databases are reduced or a database is no longer mandatory that complex quiz (ie not multiple-choice) can be performed autonomously, and that the players are not bored by repetitive questions. A quiz could also be used, for example, as a marketing tool.

Embodiment of the invention

An Internet user, i. Player visits a web page controlled by a computer system (e.g., server) to play a quiz.

The player usually registers first. As a result, his behavior can be tracked, and the computer will not ask him the same quiz questions if he wants to play a quiz again later. Manual registration is not a requirement to be able to play a quiz. You can also register using so-called. Cookies can be stored in the Internet browser of the player to a player or his computer to recognize. Registration allows the player to be automatically adjusted to the player's level by analyzing previous scores.

The player may play the quiz alone, or simultaneously with other players, or against each other (i.e., in competition). Fig. 1 shows a possible Quizablauf.

A game configuration is created for each quiz player so that the course of the quiz can be controlled, among other things. This game configuration includes all quiz relevant data. These can be various quiz data, such as the quiz duration, the number of tasks, the degree of difficulty of the tasks, the number of points reached, or so-called personal data of the player (such as language, age or place of residence) that can be considered in a quiz ,

When the quiz starts, e.g. the task block 202 the question & answer generator 100 a target criterion and receives a task with possible answers in text form back. As an alternative, task block 202 may access a database 262 that provides already-created tasks and solutions. The task may be a text (e.g., a question) or a voice file (i.e., a verbal task) that a voice converter 170 may generate. If, for example, the capital of France is to be searched for, then the target criterion includes the terms "capital" and "France". The target criteria may be automatically generated, either from existing tasks and responses stored in memory, or from entries found in task block 202 or Q & A generator 100 in database 262, or by crawling a lexicon (or database) 266) are created page-by-page (ie, from A to Z) or fed to the computer system from the outside by a script (a list of target criteria).

A database 262 can serve the storage of tasks including the associated language file, responses and player data. This makes it possible to play a quiz on a PC, tablet or phone even without an existing Internet connection.

Then, the output portal 204 presents the player with this task as text (for reading) or as a voice file (for listening), turns on the timer 205 and begins a time measurement. When multiple players are active (e.g., in the competition), issue portal 204 also ensures that all players receive the tasks simultaneously and no player is disadvantaged.

The answer is received by the input portal 206 and the elapsed time determined. To do this you read the time of timer 205 and calculate the time difference. The input portal 206 may also disable a player's ability to input if that player takes longer than a predetermined time to enter a response.

By limiting the duration of a question and answer cycle, one can increase the difficulty of the quiz. Another way to increase the level of difficulty of the quiz is by selectively selecting questions that are given to a player. Each question can be assigned a level of difficulty, e.g. from 1 to 10.

Evaluation 208 checks the player's response to their correctness. If the answer is known, i. Is part of a given set of possible answers, then the correctness of the answer is checked. Also, replies with spelling mistakes can be identified as correct because the score 208 may include an algorithm that compares the answer to the expected and possible answers. If the calculated match (probability) is large, e.g. if a word with 12 letters contains only one letter or is incorrect, it can be assumed that the player's answer is correct.

Evaluation 208 passes the result of the check to registrar 210.

Registrar 210 records the result and other parameters, e.g. Duration and difficulty of the task to take into account in the game.

Registrar 210 causes task block 202 to provide a new task. This cycle lasts as long as the quiz provides, i. it depends on the game configuration.

If the player's response received is unknown to the system, then evaluation 208 informs cache 212 and passes the task data, such as to the system. Player Response, Question and the group of possible answers.

Cache 212 may store this information in a database 264, a hard disk 548, or in memory 580 or 540.

Validator 214 checks the correctness of a player's unknown response to the system. A search engine in 214 searches for answers on the Internet 240 or in a database or lexicon. For this purpose, also the question & answer generator 100 can be used which includes a search engine 160. For example, validator 214 may access the functions in question & answer generator 100.

If the player's answer now turns out to be correct in retrospect, the evaluation 216 informs the registrar 210.

Registrar 210 may store the corresponding player data, such as the number of correct answers, correct or take into account at another time.

Registrar 210 also ensures that the checked response is stored in database 262, i. Becomes part of the group of possible answers of the task in question.

If the evaluation 216 can not judge the answer in question with high probability, then this circumstance is communicated to the marker 218.

Marker 218 annotates the corresponding data in database 264 with the result of the analysis performed by validator 214.

A person responsible for the quiz, e.g. an administrator, can then manually edit (i.e., resolve) the open tasks stored in the database 264 and ensure that the database 262 with these tasks is updated by the matching function 220.

The process of manually analyzing an open task and answering it by an administrator is called the semi-automatic mode of operation.

Question & Answer generator 100 and validator 214 may be implemented by means of a device as shown in FIG.

The Question & Answer Generator 100 has an interface 150 to the various computer peripherals and storage media such as databases, hard drives, RAM and Internet.

A control unit 110 ensures the correct function of 100.

The input unit 120 receives the target criterion (term) of the desired operation of the question & answer generator 100.

The output unit 130 outputs the result.

The search engine 160 searches the Internet for texts or answers based on the target criterion.

Search engine 160 makes use of an internet crawler 162 of the internet pages to search the target criteria, a scheduler 164 which temporally organizes the access to internet pages, and a download function 166 which copies the found texts on the internet into the memory.

Voice Converter 170 converts text into voice files that can be output to the player as an alternative to the text. This allows even blind players to participate in the quiz. These voice files are then processed in the player's browser and computer and output via loudspeakers connected to the player's computer.

The data processing unit 140 uses techniques of linguistic data processing (i.e., natural language processing), neural networks, artificial intelligence, and statistical methods to manipulate these texts and generate answers or questions.

Data processing unit 140 produces questions or answers from the Internet texts, and depending on the configuration, these data can also be stored in a database.

The functional sequence of a question and answer generator is shown in FIG.

Input unit 302 receives as input the target criterion.

Search engine function 304 accesses external sources, such as the Internet or available databases, such as dictionaries and databases 266. Search engine function 304 extracts the relevant texts or Internet pages with the aid of search engine 160.

Search engine function 304 stores the result in memory, internal (e.g., RAM) or external (e.g., database).

The word processor 306 processes these texts and produces the desired tasks, e.g. Questions or answers for a knowledge quiz.

Voice generator 307 includes the voice converter 170 and produces a voice file based on the input text. The generated speech file may have various audio formats, such as mp3, wav or jpeg, and depends on the output capabilities of the player's computer and browser.

These tasks can be stored by the output unit 308 in a database 262 for later use.

Such a task is a data record with different data elements.

A record may include a question, an answer, a group of possible answers, references, internet addresses (hyperlinks), difficulty level and other data elements.

Fig. 4 shows a computer system 500 with which such a quiz can be performed.

The output unit 510 allows the operator to monitor the system.

With the input unit 520, the computer system 500 can be operated and control data or terms entered.

Control unit 530 controls, for example, the screen cursor.

The storage unit 540 includes the internal memory 542, databases 544, instructions 546, and hard disk memory 548.

The signal generators 550 generate clock signals for the hardware components.

The processor 570 has a local instruction memory 572 and may include multiple processor cores.

The memory (e.g., RAM) 580 may include an instruction memory 582 and is for caching data.

Interface 590 connects to network 600 and Internet.

All components are interconnected by a bus 560 which serves for data exchange.
